Objective To investigate the clinical and laboratory characteristics of SSc patients in China. Method The data of 119 consecutive SSc patients based on EUSTAR DATABASE in Peking Union Medical College Hospital from February 2009 to January 2010 were prospectively collected and analyzed. All patients fulfilled ACR classification criteria in 1980 for SSc. Thex2 test and t-test were used to analyze the data. Results (1) Demographic data. Sex ratio (F/M) was 109/10 and the age rang was (44±12) years. There were 65 diffuse cutaneous SSc (dcSSc) patients and 54 limited cutaneous SSc (1cSSc) patients. 112 patients (94.1%) had Raynaud's phenomenon (RP), and the age of RP occurrence was 36 years (13～76 years), among which it was the initial presentation in 91 patients (81.3%) and the disease duration from RP to other manifestation was 12 months.(2) Clinical manifestations. ① The gastrointestinal manifestations (70.6%), especially esophageal involvement (56.3%), articular involvement (54.6%), pulmonary interstitial fibrosis (PIF) (58.8%) were frequently observed, but renal crisis (2.5%), heart block (0) and reduced LVEF (0) were rarely detected. ② Twenty cases (28.6%) out of 70 PIF patients denied any respiratory symptom and were confirmed by HRCT screening. The disease duration from RP to PIF was 34 months(3～352months); 3 case of 24 pulmonary artery hypertension (PAH) patients had no clinical manifestations. The disease duration from RP to PAH was 25 months (4～343 months). Nineteen patients had PIF and PAH simultaneously. ③Peripheral artery disease: SSc patients had a lower ankle brachial index (ABI) level (0.91± 0.19 vs 1.09±0.08, P<0.00l). (3) Laboratory finding. All patients had positive ANA. The positive rate of anti-Scl-70 antibody and ACA was 56.0% and 14.7% respectively. There was no serum sample positive for anti-Scl-70 antibody and ACA. The positive rate of anti-RNA polymerase Ⅲ antibody was 13%. (4) Compared the clinical characteristics and laboratory findings between dcSSc and lcSSc patients, we found that there were significant differences between dcSSc and lcSSc patients in finger ulcer (40.0% vs 20.4%), ACA positive rates (7.7% vs 23.3% , P<0.05). Conclusion The system involvements besides skin in SSc is common, especially PIF and gastrointestinal involvement. According to our data, there are fewer cases with renal crisis and heart block. Because part of patients with PIF have almost no clinical manifestations, so early screening for PIF/PAH is important for early diagnosis and intervention.

BACKGROUND: Evidence exists that inhibition of matrix metanoproteinase-2(MMP-2) secretion in the proliferating hernangioma tissue by transfection of adenovirus-active MMP-2(Ad-aMMP-2) cDNA would become an important means for treatment of proliferating hemangioma.OBJECTIVE: To investigate the influences of Ad-aMMP-2 cDNA transfection on human proliferating hemangioma growth in nude mice.DESIGN, TIME AND SETTING: A randomized, grouping, and controlled observation was performed in West China Hospital of Sichuan University between August 2003 and September 2004.MATERIALS: Eighteen BALB/c-nu/nu nude mice, weighing approximately 20 g, were included. Cavernous hemangioma specimen pathologically confirmed as proliferating hemangioma was resected from one 52-day-old female child patient.METHODS: The freshly reseoted human proliferating hemangioma specimen was sliced into small pieces with a size of 5 mm×4 mm×3 mm and subcutaneously implanted into the back of 18 nude mice within 1 hour to develop mouse models of hemangioma.Forty-five days after hemangioma implantation, 15 successful hemangioma nude mice were treated by intratumoral administration of adenovirus green fluorescent protein (Ad-GFP1 n = 51 Ad-GFP group), adenovirus-active MMP-2 (n = 5, Ad-aMMP-2 group), or the same amount of phosphate buffered saline (PBS1 n = 51 control group). Intratumoral administration was performed once every other day, for a total of 4 times.MAIN OUTCOME MEASURES: Observation of tumor volume and compadson of tumor necrosis area among 3 groups; detection of GFP expression in nude mouse; gross, hematoxylin-eosin staining, and transmission etectron microscope observation of tumor tissue morphology; determination of MMP-2 cDNA expression and microvascular density by immunohistochemistry; and detection of growth cycle and apoptosis of tumor cells by flow cytometry.RESULTS:①Ad-aMMP-2 could inhibit hemangioma growth in vivo, without marked adverse reactions. Tumor necrosis of different degrees was found in each group, and tumor necrosis area was significantly greater in the Ad-aMMP-2 group than in the control and Ad-GFP groups (P < 0.01). ②Histological sections displayed GFP gene expression in the Ad-GFP group. ③Gross observation results revealed relatively large tumor tissue in the control and Ad-GFP groups and relatively small tumor tissue in the Ad-aMMP-2 group. Hernatoxylin-eosin staining results showed that in the control and Ad-GFP groups, endothelial cells aggregated together in strip-shaped or lump-shaped appearance, and in the Ad-aMMP-2 group, there were many necrotic loci arranging in lamellar-shape appearance. Transmission electron microscope results revealed vascular endothelial cells with normal morphology in the control group and tumor cells with apparent nucleoli in the Ad-GFP group, while in the Ad-aMMP-2 group, some vascular endothelial cells exhibited chromatin pycnosis in the nucleus, forming apoptotic bodies.④ MMP-2 expression and microvascular density were significantly reduced in the Ad-aMMP-2 group than in the Ad-GFP and control groups (P < 0.05). ⑤The percentage of tumor cells in G0/G1 phase was significantly higher (P < 0.05), while the proliferating index was significantly decreased, in the Ad-aMMP-2 group than in the Ad-GFP and control groups. The Ad-aMMP-2 group exhibited higher apoptosis rate of tumor cells (P < 0.05), as well as more markedly increasing apoptosis index, than the control and Ad-GFP groups.CONCLUSION: It is feasible to block human proliferating hemangioma growth by transfeotion of Ad-aMMP-2 cDNA. The included mechanisms are to inhibit vascular endothelial cells to secrete MMP-21 thereby leading to local ischemia.

Objective To detect the expression of scleroderma-related autoantibodies, such as anti-Scl-70, anli-centromere antibody ( ACA)and anti-RNA polymerase Ⅲ ( ARA) , and their relationship with clinical features in Chinese systemic sclerosis (SSc) patients. Methods One hundred and thirty-five Chinese SSc patients from the clinical database of the Scleroderma Trials and Research Group proposed by European League Against Rheumatism's Scheroderma Trial and Research Group( EUSTAR) were consecutively enrolled. The expression of ARA, anti-Scl-70 and ACA were detected through linear immunoblotting, double immunodiffusion and indirect irnmunofluorescence, respectively. The relevance between the existing of autoantibodies and clinical manifestations was analyzed statistically. Results Among the 135 Chinese SSc patients, the prevalence of anti-Scl-70, ACA, ARA were 49. 6% , 13.3 % and 8.9% respectively. Patients with anti-Scl-70 antibody had significantly shorter disease course [(71 ±59) month vs (90 ± 103) month, P = 0.041] , higher proportion of interstitial lung disease ( P = 0. 031) but lower of pulmonary arterial hypertension (P =0.042). Modified Rodnan's skin score (P=0.008) and prevalence of facial and cervical cutaneous sclerosis (P = 0. 002) , distal (to elbow/knee ) cutaneous sclerosis ( P = 0. 004 ) and digital pitting scarring/disappear of digital pad were all significantly higher in anti-Scl-70 positive group. Patients with AC A had longer disease course ( P = 0. 036) , lower IgM level ( P = 0. 045) and were less prevalent of interstitial lung disease ( P =0. 045). Patients with ARA had higher serum creatinine and urea nitrogen level ( P ＜ 0.001) although otherwise features had unremarkable differences. Conclusion Scleroderma-related autoantibodies have relevance with different clinical manifestation and detection of these autoantibodies may be helpful to the diagnosis of SSc, organ involvement evaluation and predicting outcomes. The clinical relevances of autoantibodies in Chinese SSc patients may differ from other areas or races.

In addition to causing high disability and high fatality rates, ruptured intracranial aneurysms can also cause cognitive impairment. Although preventive surgical treatment can avoid intracranial aneurysm rupture and bleeding, patients may still have a certain degree of cognitive impairment, even in patients with good clinical recovery after surgery. There is no systematic review on the effect of different surgical methods on cognitive function, and the best surgical method is still inconclusive. This article reviews the cognitive impairment in patients with intracranial aneurysm, hoping to provide a basis for clinical treatment decisions.

Objective:To evaluate the efficacy and related factors of high-flow nasal cannula (HFNC) for the treatment of adult typeⅠ respiratory failure.Methods:The medical records of the subjects with acute hypoxemic respiratory failure supported by HFNC therapy in the medical intensive care unit between October 2017 and February 2019 were reviewed retrospectively. The patients′ baseline characteristics and the serial changes in the respiratory parameters after HFNC therapy at 1 and 24 hours were measured. Therapy success was defined as the avoidance of intubation. The subjects were divided into two groups.Results:Of the 75 eligible patients, 62.7%(47/75) belonged to success group. Overall, HFNC therapy significantly improved the physiologic parameters, such as partial pressure of arterial oxygen (PaO 2), saturation of arterial oxygen (SaO 2), respiratory rate (RR), and heart rate (HR), throughout the first 24 hours. After the adjustment for the other clinical variables, acute physiology and chronic health evaluation Ⅱ (APACHE Ⅱ), sequential organ failure assessment (SOFA), cardiogenic pulmonary edema, and PaO 2 improvement at 1 and 24 hours were associated with therapy success. The overall intensive mortality was 25.3%. However, out of 37.3% of the patients who required belonged to failure group, the mortality was 67.9%. The mortality in the failure group was associated with the use of a vasopressor and a limited PaO 2 improvement at 1 hour. Conclusions:HFNC can significantly improve the physiological parameters of adult patients with acute type I respiratory failure and avoid endotracheal intubation in some patients. The failure to improve oxygenation within 24 hours was a useful predictor of intubation. Among the failure group, the vasopressor use and failed oxygenation improvement were associated with mortality.

Objective:To investigate the hemostatic effect of epinephrine saline rinse solution in cleft palate repair.Methods:A total of 100 children who underwent cleft palate repair in the operating room of the Second Affiliated Hospital of Shantou University Medical College from 2018 to 2020 were selected, Among them, 51 were males and 49 females, aged from 6 months to 12 years, with an average (2.5±2.49) years. The patients were divided into two groups according to whether to use epinephrine saline flushing fluid: in group A, 43 cases were treated with adrenaline saline irrigation solution to wash the incision during the operation; gauze soaked in rinse solution was used to fill the oral cavity before endotracheal intubation and extubation after operation; in B group of 57 cases, no intraoperative rinses were used. The intraoperative blood loss and operation duration were compared between the two groups.Results:Intraoperative use in group A after adrenaline saline rinses showed that the intraoperative blood loss of children (16.23±4.88) ml was significantly lower than that of group B (19.26±4.13) ml. The duration of operation in group A (109.79±40.27) min was significantly shorter than that in group B (137.16±50.47) min, The difference was statistically significant ( t=2.92, P<0.05). Conclusions:The incision is rinsed with epinephrine saline solution during cleft palate repair. In addition, before endotracheal intubation and extubation after operation, gauze soaked in rinsing solution is used to fill the oral cavity, which could significantly reduce the amount of bleeding and shorten the operation time.

To investigate the distribution and clinical significance of nuclear dense fine speckled (DFS) pattern in various diseases. A total of 95 289 patients who received DFS tests at Peking Union Medical College Hospital from January 2019 to December 2020 were included in this study. The results of indirect immunofluorescence assay (IIF) for detection of antinuclear antibody (ANA) were evaluated. The positive rates of ANA and DFS were 39.60% (37 733/95 289) and 1.19% (1 139/95 289) respectively. The positive rate of DFS in ANA-positive patients was 3.02% (1 139/37 733). DFS and ANA positivity were significantly different among different age groups rather than gender. The positivity rate of DFS reached the peak (55.57%, 633/1 139) in young patients between 21-40 years, while positive ANA with negative DFS was mainly observed in patients between 41-60 years (37.26%, 13 636/36 594). Additionally, single ANA-positivity were mainly detected in rheumatology department (59.23%, 18 402/31 066), whereas positive DFS was more common in obstetrics and gynecology department (3.08%, 49/1 593). There were 82.88% (944/1 139) patients with positive DFS diagnosed with non-autoimmune disease (non-AID), and 19.49%(222/1 139) with dermatosis. Positive DFS with higher titer (≥1∶320) was detected more frequently in autoimmune disease (AID) patients (5.13%, 10/195) than in non-AID patients (1.69%, 16/944) ( P<0.05). The DFS pattern is rare in ANA positive patients, which is mainly observed in women between 21-49 years. High titer of DFS is prevalent in AID patients, but positive DFS is detected more in non-AID patients, especially those with dermatosis.

OBJECTIVETo assess the impact of metabolic syndrome(MS) on Framingham risk score(FRS) in patients with type 2 diabetes mellitus (T2DM).

METHODSThe anthropometric and biochemical data of 1708 patients with T2DM admitted in hospital from May 2008 to April 2013 were retrospectively analyzed, including 902 males and 806 females with a mean age of 57.1±11.8 years (20-79 years). Diagnosis of MS was made according to the criteria of the Adult Treatment Panel Ⅲ Criteria modified for Asians.

RESULTSCompared to non-MS/T2DM patients, MS/T2DM patients had higher waist circumference, body weight, body mass index, systolic and diastolic blood pressure, fasting C peptide, total cholesterol, triglyceride, and LDL-C (P<0.05), while lower HDL-C (P<0.01). Both FRS [13.0(10.0, 15.0) vs 11.0(9.0, 13.0) in male,15.0(12.0, 18.0) vs 12.0(6.0, 14.8) in female,P<0.01)] and 10-year cardiovascular risk [12.0%(6.0%, 20.0%) vs 8.0%(5.0%,12.0%) in male,3.0%(1.0%, 6.0%) vs 1.0%(0.0%, 2.8%) in female,P<0.01] were higher in MS/T2DM patients than those in non-MS/T2DM patients.Both FRS and 10-year cardiovascular risk were increased with the components of MS.

CONCLUSIONT2DM patients with MS have more cardiovascular risk factors, higher FRS and 10-year cardiovascular risk.
